1 D IVIDING F RACTIONS Lesson 25

2 B ASIC F RACTIONS R EVIEW : *Change a whole # to a fraction  Write a 1 underneath *Reciprocals  A flipped fraction (based on given fraction) 5 = 5 18 = 18 1  5 5 1

3 D IVIDING F RACTIONS In all truth and reality, fractions can NEVER be divided! They can only be MULTIPLIED !!!!

4 D IVIDING F RACTIONS Steps: 1) KEEP the first fraction the same. 2) CHANGE the “ ÷ ” to “x” 3) FLIP the second fraction to its reciprocal 4) [Cross Reduce &] Solve OR Solve [& Reduce] 3 ÷ 2 4 5 2 ÷ 3 3 4 3 ÷ 9 4 10

5 D IVIDING FRACTIONS - P RACTICE Remember – Everything MUST be in fraction form! Keep Change Flip Solve (Reduce if possible) a) 3 ÷ 2 5 3 b) 5 ÷ 5 7 c) 5 ÷ 2 6 3
